2345.com is a browser hijacker directed to Chinese users
2345.com is a suspicious search engine which hijacks Google Chrome, Internet Explorer, Mozilla Firefox or other browser and modifies its settings without permission. The modifications enable the virus to restrain users from the ability to revert these settings to default. This questionable app is distributed with bundling; for that reason, it is also considered to be a potentially unwanted program[1] (PUP).
| Name | 2345.com |
| Type | Browser Hijacker |
| Danger Level | Low |
| Symtoms | Hijacked search engine and homepage; intrusive ads and redirects |
| Distribution | Bundling, suspicious websites |
| Elimination | Manual or automatic – FortectIntego recommended to uninstall 2345 virus |
From the first glimpse, one can notice, that it is primarily directed to Chinese speaking users (however, as the internet is worldwide, 2345.com hijack can occur anywhere). You can also notice a search engine BaiDu – a Chinese equivalent to Google.com (standard search engines are not allowed in China, as the worldwide internet is heavily censored). However, if you check the number of quick access links and adverts present on the website – it raises suspicions immediately.
The suspicions are totally justified, as this browser hijacker tends to manipulate users' searches, distribute an excessive amount of ads, redirect users to sponsors' and questionable domains and gather a significant amount of non-personally identifiable information.
All these measures are taken so that the developers of the virus could gain monetary benefit from unsuspecting users. However, the typical internet surfer gains nothing in return – just the opposite. Therefore, if you saw that this PUP acquired access to your system, do not delay 2345.com removal. The quickest elimination can be performed using a robust security tool – FortectIntego.
Pop-up ads and banners might hinder the background of official websites, making them much less appealing and less informative. Additionally, some words on a site might be turned into hyperlinks, performing the same function as ads do – promote unknown content from sponsors. This way, the unknown page rank or sales of affiliate websites increase.
2345.com redirects can bring victims to suspicious domains, such as illegal software, porn, phishing, fake updates or even malware-infiltrated sites. These websites might run malicious JavaScrips to download and install malware (such as ransomware – a dangerous virus which locks up users files and renders them unusable) which can severely damage the computer or steal personal data. The latter can be used for such illegal activities as identity theft or money snatching from the bank account.
As it is typical of browser hijackers, 2345.com collects an enormous amount of non-personally identifiable information. This can include, but is not limited to:
- IP address
- Geo-location
- System used
- ISP[2]
- Search queries
- Websites visited
- Clicks on links, etc
Thus, if you want to keep your search history private, we suggest you stay away from 2345.com browser extension. Additionally, all the personal information you enter via hijacked engine might get compromised and end up in crooks' hands.
Because your Internet Explorer, Google Chrome, Mozilla Firefox, Safari (or any other browser) is continuously strained to display as many advertisements as possible, its performance might decrease significantly. So, not only you have to deal with invasive ads, but also bear the burden of slow loading speed or browser crashes. We hope that after reading this article you will decide to remove 2345.com as soon as possible.
Bundling helps PUP developers spread their programs
If you wonder how the uninvited guest approached your computer – you should probably check if you recently installed some free software from the internet. Bundling is a remarkably successful marketing campaign, practiced by freeware developers. Security professionals[3] concluded that users typically do not look for questionable apps which modify their browser settings themselves.
Thus, it is essential to be attentive when installing free software, such as PDF creators, media players, questionable system optimizers, etc. To avoid future infections, follow these simple tips:
- Search for legitimate software and never rely on cracked/illegal one – it can infect your computer with viruses;
- No matter what, never rush the installation procedure and read through instructions carefully;
- Read through EULA/Privacy Policy;
- Never click “Next” button quickly;
- When prompted, always pick Advanced/Custom installation mode instead of Recommended/Quick one. It will allow you to decline any additional components included in the installation package.
Being careful will save you from a lot of potential distress. Therefore, do not rush and you will not have to deal with an unwanted application at all!
